Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7372, here are decompositions:
- 3 + 7369 = 7372
- 23 + 7349 = 7372
- 41 + 7331 = 7372
- 89 + 7283 = 7372
- 179 + 7193 = 7372
- 251 + 7121 = 7372
- 263 + 7109 = 7372
- 269 + 7103 = 7372
Showing the first eight; more decompositions exist.
